AEC algorithm delay with XKVF3100

Post by andy wong »

hi,everyone
I had a problem with the 3100 that when I used the 1i0o0_I2S_ONLY_48KHz_C43 to build the configuration, the delay of the sound from the microphone board input to the horn output was more than 50ms. I realized that this could be a delay for far-end stuff (beamform AEC AGC etc), is my guess correct? If right, I can turn off some functions such as AEC, because I am on-site equipment.
If anyone is willing to answer my question I will be very happy
Wish you a Happy New Year!

ok, I want to use XK VF3100-C43 to do a live conference system. I want to use KIT directly to achieve my function, but I found that the algorithm provided by the library has a long time about the processing delay. What I mean is that the sound goes from the microphone to the speaker output after 50ms, which is something I can not accept ... so is there any way to solve it?
